Example Embodiment

[0027] Example 1

[0028] Reference Figure 1-4 , The present invention provides a drying device for electrolytic copper foil, comprising an unwinding roll 1 and a winding roll 2, and an electrolytic copper foil (not shown in the figure) is wound between the unwinding roll 1 and the winding roll 2. The winding roller 2 pulls the electrolytic copper foil to rewind, and drives the unwinding roller 1 to unwind. A box 3 is provided between the unwinding roller 1 and the wind-up roller 2, and the box 3 is provided with a guiding mechanism. The bottom of the guide mechanism is provided with an air intake mechanism, the top of the guide mechanism is provided with a heat treatment mechanism, one side of the guide mechanism is provided with a drive mechanism, and the guide mechanism is provided with a friction mechanism;

[0029] The friction mechanism includes a plurality of rollers 4 arranged on the guide mechanism. The driving mechanism drives the roller 4 to rotate. The rotation directi...

[0040] Example 2

[0041] Reference Figure 5-7 , The two ends of the air collecting pipe 13 are respectively connected with extension pipes, the two ends of the two extension pipes 33 are respectively connected with two pipes 34, the pipes 34 are perpendicular to the extension pipe 33, A pressure nozzle 35 is fixed at the top, the angle between the spray directions of the two pressure nozzles 35 is not greater than 180°, and one side of the arc-shaped cover 25 is provided with a transition opening 36, which is an arc The pressurizing nozzle 35 faces the transition opening 36. A part of the hot air in the air collecting pipe 13 enters the pressurizing nozzle 35 through the extension pipe 33 and the duct 34, and the pressurizing nozzle 35 pressurizes the hot air to the transition The opening 36 is ejected. When the push rod 20 draws air, part of the hot air flows to the joint between the air outlet pipe 24 and the arc-shaped cover 25. At this time, the part below the arc-shaped c...

Abstract

The invention discloses an electrolytic copper foil drying device. The electrolytic copper foil drying device comprises an unwinding roll and a winding roll. A box is arranged between the unwinding roll and the winding roll. A guide mechanism is arranged in the box. An air inlet mechanism is arranged at the bottom of the guide mechanism. A waste heat treatment mechanism is arranged at the top of the guide mechanism. A driving mechanism is arranged on one side of the guide mechanism. A friction mechanism is arranged on the guide mechanism. The friction mechanism comprises a plurality of rollersarranged on the guide mechanism. The driving mechanism drives the rollers to rotate. The rotating direction of the rollers is opposite to the driving direction of electrolytic copper foil. Each roller is internally provided with a through cavity. The surface of each roller is provided with a plurality of rows of exhaust hole sets sequentially arranged at intervals. Hot air is supplied into the cavities through the air inlet mechanisms. The hot air is discharged from the exhaust hole sets and collected through the waste heat treatment device. The waste heat treatment device cyclically discharges the collected hot air to the electrolytic copper foil in a pressurization mode. The electrolytic copper foil drying device can dry water stain on the surface of the electrolytic copper foil to prevent secondary rusting and oxidation.

Description

technical field [0001] The invention relates to the technical field of electrolytic copper foil production, in particular to a drying device for electrolytic copper foil. Background technique [0002] Copper foil is an important material for the manufacture of copper clad laminates and printed circuit boards. In the rapid development of today's electronic information industry, electrolytic copper foil is known as the "neural network" of electronic product signal and power transmission. Copper foil is easily polluted by grease and sweat during transportation and storage, and its surface activity is large. It is easy to produce an oxide layer on the surface, so copper foil must be degreased and pickled before rough treatment. However, the existing copper foil surface pretreatment device is not equipped with a drying device, which is inconvenient for workers to dry the water stains on the copper foil surface, thereby causing secondary rust and oxidation to occur.
